3A Molecular Sieve High Quality Desiccant 3A Zeolite Price Molecular Sieve Adsorbents for Gas Drying
Applications
- Drying of unsaturated hydrocarbons (e.g. ethylene, propylene)
- Cracked Gas Drying
- Drying of natural gas, if COS minimization is essential, or a minimum
co-adsorption of hydrocarbons is required.
- Drying of highly polar compounds, such as methanol and ethanol
- Drying of liquid alcohol
- Static, (non-regenerative) dehydration of insulating glass units, whether air
filled or gas-filled.

The preparation of 3A molecular sieve usually involves the following steps:
Raw material preparation: such as water glass, solid aluminum hydroxide, sodium hydroxide, etc.
Solution preparation and mixing: water glass is boiled with steam to form an aqueous solution with a certain density, and impurities are removed by settlement; The solid aluminum hydroxide and sodium hydroxide are heated and dissolved in a certain proportion to produce sodium metaaluminate solution for use.
Gel generation and crystallization: water glass, sodium metaaluminate, sodium hydroxide are mixed according to a certain molar ratio, and after a certain reaction time under agitation, temperature is raised to crystallize, and crystal powder is obtained.
Ion exchange and activation: After filtration and washing, potassium chloride is added for ion exchange (the exchange degree is usually 40%), then filtration and washing, drying, adding adhesive kneading, molding, burning activation, and finally 3A molecular sieve is obtained.
